The broadcast nature of wireless transmission is always vulnerable to eavesdropping. Hence the security of such networks is of utmost importance, and consequently, physical layer security (PLS) has emerged as a viable solution [1]}.
The authors in [2]}, [3]}, [4]} have studied various optimization techniques to maximize the secrecy rate of RIS enabled wireless systems and designed the jointly optimal transmit beamformer and RIS phase shift matrix. The above papers consider performance optimization rather than secrecy performance analysis. The secrecy performance of an RIS-aided indoor communication system via secrecy outage probability (SOP) and
average secrecy rate is considered in [5]} assuming Rician fading model. The SOP is also derived assuming a Rayleigh fading model in [6]}. These papers do not consider friendly jamming to enhance the secrecy performance or optimize the SOP performance using power allocation.
